I have exported the extended private key from mobile wallet and tried to convert to get the private the key, private key wif and address with following code
const ecc = require('tiny-secp256k1')
const { BIP32Factory } = require('bip32')
const { ECPairFactory } = require('ecpair');
// You must wrap a tiny-secp256k1 compatible implementation
const bip32 = BIP32Factory(ecc)
const bitcoin = require('bitcoinjs-lib');
const ECPair = ECPairFactory(ecc);
// Extended private key
const xprv = 'xprv_MY_EXTEND_PRIVATE_KEY';
// Derive the private key for a specific address using path
const node = bip32.fromBase58(xprv, bitcoin.networks.mainnet).derivePath("m/44'/0'/0'/0/0");
//const node = bip32.fromBase58(xprv, bitcoin.networks.mainnet);
const privateKey = node.privateKey;
// Convert the private key to a private WIF
const privateWif = ECPair.fromPrivateKey(privateKey).toWIF();
// Derive the public key and Bech32 address
const publicKey = ECPair.fromPrivateKey(privateKey).publicKey;
const { address } = bitcoin.payments.p2wpkh({ pubkey: publicKey });
console.log("Private Key: ", privateKey.toString('hex'));
console.log("Private WIF: ", privateWif);
console.log("Public Key: ", publicKey.toString('hex'));
console.log("Bech32 Address: ", address);
Then I have tried to send a transaction using the following code
`const fromAddress = keys.BITCOIN_PUBLIC_KEY.key;
const ECPair = ECPairFactory(ecc);
const MAINNNET = bitcoin.networks.mainnet;
const keyPair = ECPair.fromWIF(keys.BITCOIN_PRIVATE_KEY.key, MAINNNET);

But my transaction fails with follow error
I am using bech32 address.

Below is the error
